"A 'Mineral Resource' is a concentration or occurrence of material of intrinsic economic interest in or on the earth's crust in such form, quality and quantity that there are reasonable prospects for eventual economic extraction. Mineral Resources are further sub-divided, in order of increasing geological confidence, into inferred, Indicated and measured Categories. Inferred Mineral Resource is the part of a mineral resource for which tonnage, grade and mineral content can be estimated with a low level of confidence. It is inferred from geological evidence and assumed but not verified geological or grade continuity. It is based on information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes which may be of limited or uncertain quality and reliability.

February 13, 1925) was an American cave explorer, principally in a region of Central Kentucky that houses hundreds of miles of interconnected, underground caverns within Mammoth Cave National Park, the longest cave system in the world. In the early 20th century, in an era known as the Kentucky Cave Wars, commercial cave owners and explorers in Kentucky entered into a bitter competition to exploit the bounty of caves for commercial profit from tourists, who paid to see the caves. On January 30, 1925, while trying to find a new entrance to Crystal Cave (also known as "Sand Cave" by the media) , Collins became trapped in a narrow crawlway, 55 feet (17 m) below ground. The rescue operation to save Collins became a national newspaper sensation and one of the first major news stories to be reported using the new technology of broadcast radio. The rescue attempt grew to become the third-biggest media event between the world wars.". Very Good+ .

"The San Francisco Bay region is underlain by some of the most complex and active geology in the world. The earth here is made up of everything from iron- and magnesium-rich rocks formed deep in the interior of our planet to sand and gravel recently deposited by our streams and rivers. All of these rocks are constantly being bent and tilted by the forces that also drive our San Andreas, Hayward, and other faults. The same forces that cause earthquakes have shaped the landscape that makes our region unique: the hills, the valleys, and the Bay itself. ". Very Good+ .
